Question 57

HOTSPOT -

You have an Azure Data Lake Storage Gen2 service.

You need to design a data archiving solution that meets the following requirements:

✑ Data that is older than five years is accessed infrequently but must be available within one second when requested.

✑ Data that is older than seven years is NOT accessed.

✑ Costs must be minimized while maintaining the required availability.

How should you manage the data? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.

Hot Area:

    Correct Answer:

    Box 1: Move to cool storage -

    Box 2: Move to archive storage -

    Archive - Optimized for storing data that is rarely accessed and stored for at least 180 days with flexible latency requirements, on the order of hours.

    The following table shows a comparison of premium performance block blob storage, and the hot, cool, and archive access tiers.

Discussion
sagur

If "Data that is older than seven years is NOT accessed" then this data can be deleted to minimize the storage costs, right?

Massy

I agree, should be deleted

KashRaynardMorse

Deleting data older than 7 years is not an option available in the answer list. Becareful of the gotcha; 'Delete the blob' is an option but it would delete all the data, included the ones that are e.g. 5 years old. So you can't choose that answer. So the next best thing to do is to put it into archive.

Boompiee

I'm confused by your comment. It clearly does state an option to delete the blob after 7 years.

Aditya0891

whet he meant to say is all the data be it in hot, cool or achieve resides in the blob. So if you delete the blob it will delete all the data be it 5 years or 7 years or more recent data in hot tier. Delete blob option is just to make it a tricky question

temacc

Why it will delete data in hot tier? I have a blob. Blob between 5 and 7 go to cool, more than 7 delete.

vctrhugo

God no... A single piece of data could be a BLOB (Binary Large OBJECT).

shakes103

Be careful with wording. Any answer given must be an "Archiving solution" & Delete the blob is not an archiving solution.

AnonymousJhb

of course it is.

noobprogrammer

Makes sense to me

vernillen

Most important part about that question is "Costs must be minimized while maintaining the required availability.". So deleting isn't an option, since it won't be available anymore. So ARCHIVE seems correct

Gikan

The documentation, which is linked into the answer: "Archive tier - An offline tier optimized for storing data that is rarely accessed, and ..."

PeteZaria

Answer is correct. RE: Why is 'Delete the blob' not a valid option? Well I agree that 7 years may seem a long time to most who commented here BUT there is ABSOLUTELY NO mention to DELETE here, In several context NOT ACCESSED can easily refer to be drawn OFFLINE in ARCHIVE IOW: "Your data files may be stored in the archive access tier in Azure Blob storage based on different context needs. According to the Azure documentation: While a blob is in archive storage, the blob data is OFFLINE and CANNOT BE ACCESSED that is: read, copied, overwritten, or modified. You also can't take snapshots of a blob in archive storage. However, the blob METADA remains online and available, allowing you to list the blob and its properties. For blobs in archive, the only valid operations are GetBlobProperties, GetBlobMetadata, ListBlobs, SetBlobTier, and DeleteBlob. For more information about Azure Blob storage tiers, see the Azure documentation: https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-storage-tiers.

GodfreyMbizo

The Given answer is correct,the big tip here is archiving solution,deleting is not archiving solution

dgerok

1) Cool, because it takes hours to access Archive data, but cool is cheaper than Hot 2) archive. For those, who thinks, that "Data that is older than seven years is NOT accessed" is equal to "the data can be deleted", you're fired :)

Sr18

Damn Right!! With my 10 years exp never ever delete the data until its being asked by business owners for cost reduction. It will end up reduction in work force in form of you.

otapi

Why would keep any data in archive if it is NOT accessed? That would be just waste of money and possible violation of give data protection regulations.

kkk5566

correct

rlnd2000

In my opinion, the retention policy clearly states that any file or blob older than seven years is a violation. The policy specifies: "Data that is older than seven years is NOT accessed." Therefore, any data older than seven years should be deleted to avoid unnecessary costs, as we should not pay for storage we don't need. This approach aligns with the requirement to "minimize costs while maintaining the required availability." For data retention: Data older than five years should be moved to the cool storage tier. Data older than seven years should be deleted.

LittleSoap

Data older than 7 years old is NOT accessed. Archived blobs are not accessible and deleting the blobs would be too aggressive so I'll go with archive for the second answer with the question as is.

Alongi

Cool Storage and Delete job, because in this way you can seriously minimize costs

dataalex

i think you guys are really overthinking it. just f....g delete data that will never be accesed.

Charley92

Costs must be minimized while maintaining the required availability. -- > DO NOT DELETE

d046bc0

correct. deleting files is not a type of archiving them (chatGPT)

hassexat

Cool & Archive No deletion of data here because question require to perform a data archiving solution

Saintu

The question says: ✑ Provides the highest degree of data resiliency and this would be RA-GZRS with customer failover. Data is replicated to 3 zones in the primary region and async to a secondary region. If primary zone fails, there is read and write to other zones in the region. Microsoft only engages a failover if "original primary region is deemed unrecoverable within a reasonable amount of time due to a major disaster.", which is not the case here. The answer provided is correct

auwia

"Costs must be minimized while maintaining the required availability." ==> it means Move to archive storage"

sumanthss

Archive might be the right option as we need to retrive before we access the data. so we cannot access without retrieval.

cgarciamarco1

Why is 'Delete the blob' not a valid option? Given that seven years data is not accessed, why don't we delete the blob?
